I have just realized that this patch (1/2) will not apply against media tree because it does not have commit 27b76486a3 (media: mx2_camera: remove cpu_is_xxx by using platform_device_id), which changes from mx2_camera.0 to imx27-camera.0. So it seems to be better to merge this via arm tree to avoid such conflict.

This is exactly the reason why I wasn't able to merge it. The problem was, that this "media: mx2_camera: remove cpu_is_xxx by using platform_device_id" patch non-trivially touched both arch/arm/ and drivers/media/ directories. And being patch 27/34 I didn't feel like asking the author to redo it again:-) This confirms, that it's better to avoid such overlapping patches whenever possible. > So it seems to be better to merge this via arm tree to avoid such conflict.

I agree with Fabio and Guennadi. There are so many changes happening at arm that merging those two patches there will likely be easier for everybody. Otherwise, I'll need to pull from some arm tree that never rebase, with the needed patches, and coordinate with you during the merge window, to be sure that patches will arrive there at the right order, from the right tree.

Hopefully these kind of cross dependencies become fewer over time. SoC code is getting smaller and gets better abstracted from the drivers, so chances are good. Sascha
